Description

Technical Field

[0001] The utility model belongs to the technical field of construction quality control of deformation joints of concrete structures, and in particular relates to a clamp device for improving the construction quality of deformation joints. Background Art

[0002] With the continuous development of the construction industry, construction is constantly moving towards the trend of refinement. For the construction of deformation joints such as expansion joints and settlement joints, asphalt fir boards are generally used as caulking boards, but general formwork does not have a limit device for asphalt fir boards. Since the installation of a limit device on the formwork will reduce the scope of application of the formwork, it cannot meet various design requirements and will reduce the economic benefits of the formwork, so that no manufacturer produces this formwork. Therefore, during the construction of deformation joints, due to the lack of certain fixing measures, the impact force of concrete pouring often causes the joints to be not straight or unable to form through joints. For this reason, finding a simple and efficient reinforcement measure is a major measure to achieve refined construction of structures. Utility Model Content

[0003] When it comes to the construction of expansion joints of structures, during the construction of expansion joints, the asphalt fir boards often deviate when impacted by concrete due to the lack of fixing measures, resulting in poor joint quality. In addition, there are currently no targeted templates on the market, and the joint quality is difficult to guarantee. The joint quality further affects the appearance quality and also leads to an increase in the cost of rework in the later stage. In view of the above problems, the purpose of the utility model is to provide a clamp device for the construction of expansion joints, which can effectively fix the filling plates, optimize the joint quality, reduce the rework cost, and further promote refined construction.

[0006] Preferably, a nail hole is provided at the bottom of the first template positioning sheet.
